Individual Certification   

  • Lead Disciplines: The Lead Disciplines Table (P-00848, PDF, 47 KB) lists the training courses, fees, and any state exam, prior education, or experience required for certification in each discipline.
  • Training: An individual must first complete accredited lead training before applying for certification.  Select Lead Training Providers for the list of trainers.
  • Affiliation with a Certified Company: An individual conducting regulated lead work must work for or own a Wisconsin-certified Lead Company or Lead-Safe Company.  To apply for company certification, complete the Certification Application - Company (F-00171, PDF, 25 KB).  
  • Application: After completing training for a lead discipline, the individual may:
    • Apply online, if paying by VISA or MasterCard.
    • Mail a paper application (F-44003, PDF, 43 KB), if paying by check or money order. 
    • Applicants who completed required training in another state must apply using the paper application form (F-44003, PDF, 43 KB), following the special directions on Page 2.
  • Application Processing: Applications are processed as quickly as possible.  Applicants are encouraged to apply immediately after completing training, and to submit renewal applications at least 30 days before the expiration date on the current card.
  • Certification Cards: Individuals must have their certification card at the job site when conducting regulated lead work. 
  • State Lead Exam: Individuals applying for initial certification as a Lead Abatement Supervisor, Inspector, Hazard Investigator, or Risk Assessor are required to take the state lead exam for the discipline.
    • Applicants must pass the appropriate exam with a score of at least 70% correct within six months of completing their qualifying training.  Persons who were not previously certified in the discipline are issued a six-month Interim Certification card, allowing them to conduct regulated work while waiting to take and pass the exam.
    • A person who fails the exam may take it up to two additional times during the initial six-month period. Each exam registration costs $50.
    • A person who does not pass the exam after three attempts, or within six months, whichever comes earlier, must retake the initial course for the discipline before again taking the exam. This person would not qualify for Interim Certification again and would not be allowed to conduct regulated work until passing the exam and receiving a certification card.
    • An applicant currently certified in another state who passed the exam in that state may provide proof of certification in that state and of passing that state's exam in lieu of taking the Wisconsin exam.
    • Persons who have passed the exam in Wisconsin but whose certification has been expired for more than 12 months are required to retake the state exam prior to qualifying for recertification. Persons may also be required to retake the initial course if they did not maintain their refresher training requirements.
  • Exam Schedule, Location and Registration Information
  • Exam Study Guides: Topics covered on the exams are available for the Supervisor, Inspector, Hazard Investigator, and Risk Assessor exams.
